Introducing Zuma and Ojai – Pedal Power Supplies

EDIT: Zuma and Ojai available now!

Buy Zuma ($249) |  Buy Ojai ($149)



We hope 2016 has been great for you so far. It’s been pretty exciting for us, and today we can finally tell you about two of the big projects that we’ve been working on! Over the last few years our analog design team (Gregg and Josh) have been diligently working on technology that dramatically enhances the way pedals can be powered. We’re happy to announce our Zuma and Ojai high current DC effects pedal power supplies!

Zuma and Ojai - High Current DC Pedal Power Supplies

Like everything we work on—we only want to develop and release products where we truly believe we’re bringing something new to the world of musicians. And it helps if these projects are incredibly fun to work on! We’re still a super small group of engineers and music nerds, and like you we’re fanatical about sound and the creation of music.

Why Power?

Over the last several years, some of the most common questions we’ve been asked are related to power. How do I properly power my pedals? Why am I getting this strange noise? What’s isolated power? Should I daisy chain my pedals? What outlet should I use? Why can’t my power supply handle all of my pedals? Why did I just blow up my pedal?

We learned that many of our customers were not entirely happy with the power options that are available. We felt it was time for us to try something new and bring some different ideas and fresh technology to this arena.

You may not know this, but Strymon analog design gurus Gregg Stock and Josh Forbes collectively have an incredibly rich history designing power supply systems for a wide range of industries. From mission-critical power systems for the aerospace industry, to best-in-class power supplies for top-selling power amplifiers, studio monitors, guitar amplifiers, and more. Power is one of their true passions, and we want to bring this passion to the world of effects pedals.

This is an incredibly exciting intersection for us. To bring our power expertise the world of pedals, to eliminate the worry that goes into powering pedals properly, and to allow you to focus on being creative rather than thinking about power.

Zuma - High Current DC Effects Pedal Power Supply


Zuma is the highest horsepower, most technologically advanced effects pedal power supply of its kind. You get 9 high-current, individually isolated, ultra-low-noise outputs, each providing a massive 500mA of current. The dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering allow your pedals to achieve their highest possible dynamic range. With automatic international power compatibility built-in, you can take Zuma to any stage in the world.  Zuma is also part of an expandable system—you can add more outputs by connecting an Ojai (or even more than one Ojai) to the 24V Out jack.



Ojai is the highest horsepower, most technologically advanced effects pedal power supply of its size. You get clean, rock-steady power in a lightweight and expandable package, giving you flexibility and room to grow. Ojai has five high-current, individually isolated, ultra-low-noise outputs—each providing a huge 500mA of current. The breakthrough power technology within Ojai will allow your pedals to achieve their highest possible dynamic range. Like Zuma, Ojai can work on any stage anywhere in the world, and is part of an expandable and modular system.

Pricing and Availability

Ojai will be available in Spring of 2016, for US $149. Zuma will be available in Summer of 2016, for US $249. International pricing is not yet announced. We’ll be adding more information, videos, and even a power white paper to our site in the coming weeks. If you’d like to be notified about exact availability, please sign up for our email newsletter.

Happy creating! – Ethan

  1. Hi Ethan I already have made up my mind to get the Ojai. Will be getting the Blue sky as well from a Strymon dealer here in Philippines where I have bought some pedals as well , from Spud Music. Will contact him tomorrow for reservations. I like to know the dimensions of the Ojai itself and the power adaptor if you can email me coz I need to refigure my board which is a tray type live in board with no space underneath. Thanks I am so stoked that you guys finally answered a prayer I was saying that if only you can make a power supply for your pedals in a very small footprint but with great power capabilities. And voila here you are! Thanks so much!


    1. Hi Ritch, We should have final specifications over the coming weeks and will post once it’s confirmed. I’ll make a note to email you when it’s posted. 🙂 Thanks!

      1. It doesn’t fit with pedaltrain nano, the old version of the nano have a plate in the back i had mine attached with velcro there, the new version is incompatible

    1. @Devin Pevey – Thanks for contacting us! 🙂 There are fuses, however they are not user serviceable. As there are built in protection circuits, if these ever blow, this means there is a catastrophic failure elsewhere.

    1. @Algirdas – Thanks for checking out the power supplies! 🙂 Ojai and Zuma are not yet in production. Final dimensions and weight are subject to change. Here are the current dimensions:

      Ojai dimensions: 3.2″ x 2.3″ x 1.3” (81mm x 58mm x 33mm)
      Ojai power adapter dimensions: 4.2″ x 2.15″ x 1.25” (107mm x 55mm x 32mm)
      Zuma dimensions: 6.8″ x 3.3″ x 1.8” (173mm x 84mm x 46mm)

  2. I love your gear! I already own a Timeline and an el Capistan; am about to buy a Flint. I’d rather hook all three up to the Ojai than use 3 separate A/D adapters, obviously. My question is : are you offering any kind of rebate or exchange program on the A/C adapters your customers already own? I’d like to trade the two I have back, and get the Flint without an A/C adapter to begin with – just get an Ojai with (included?) jumper cables and have at it. Please advise.
    Also, do you have Timeline user preset blank sheets somewhere downloadable on your site?
    Thanks for everything! Jeff

    1. @Jeff Westerman – Thanks for supporting Strymon! 🙂 We will not be providing any type of exchange/rebate program for the power supplies that come with the pedals. The Ojai power supplies do not have an official release date and are slated to be released sometime during this coming Spring.

      Also, we currently are working on getting some links working on our site which includes providing the TimeLine Factory preset list which has blank spots available to note your own settings with:

        1. Hi Culin, Ojai is now available for pre-order and shipping soon. Zuma will be later towards end of summer. We don’t have an exact date, but will provide updates as it gets closer to release. You can visit Ojai at Thanks 🙂

  3. Looks like another instant hit, Strymon! Looking forward to the purchase. Now we all want to know; how many Ojai can you power at once with the Zuma?

    1. @Zachary Drummond – Thanks for the support! 🙂 You can theoretically link as many as 20 Ojai units to Zuma. The amount of available current per output depends on the current draw of the connected pedals. A common setup would be to link 1 or 2 Ojai units to Zuma.

  4. Hello, when will the Zuma be available in Europe (Austria / Germany ) I’m just selling my actual power supply from Cioks to get a Gigrig System but I’ve seen your Zuma on Youtube and the absolutely high quality compared to the plastic gigrig stuff blew me away. Problem is, I would need the new powersupply soon. I know you haven’t fixed any date but it would really help me if you can just tell me if it’s at the same time as the US release or if it takes longer for Europe?

    1. @Alexander – We currently have the Zuma set to release sometime during the Summer, but there is no fixed date for that at this time. A European release for the Zuma would be sometime after the US release, but I cannot provide much more detail than that I’m afraid.

  5. Hello there!

    My name is Thiago, I’m from Brazil and would like to ask you guys if ZUMA and OJAI will be able to power the Eventide H9 properly.
    I hope sooo much for a “yes” as the answer. hahaha
    Would be like heaven to power up my blue sky, el capistan and H9 in only one power supply!
    I also would love to know something about the release dates and prices! 🙂

    Thanks so much for your attention!
    Thiago Vaz

    1. @Thiago Vaz – Thanks for checking out the blog! 🙂 To power an Eventide H9, you would need to get a reverse polarity power cable so that you can provide the H9 with 9V 500ma with center-positive power.

      1. I just purchased the Zuma. Does it come with reverse polarity cables too power eventide type pedals? If not, where can I buy them? Thx! -Lou

        1. @Lou Blanco – The Zuma does not come with reverse polarity adapters, however, we will have those available on our online store soon. You can use reverse polarity adapters from other manufacturers as they will work the same.

  6. Hello

    big love and respect Strymon

    happy owner of Bigsky/Timelive and Mobius in Scotland here 😉

    heavily looking forward to the release of Ojai, will be nice to free up some plugspace and run all 3 of those badboys from the one source!!!!!

    Please keep me posted in regards to the setup for UK power settings that I’ll have to apply to have this all running safely, wouldn’t want to damage the pedals!!

    any further info on release date/price is most welcome!


    1. @stephen – Thanks for supporting Strymon! 🙂 When they are released, the Ojai power supplies will work worldwide with voltages from 100V-240V while the output specs will remain the same at 9V DC 500mA center-negative. Pricing is set for $149US and will be released later this Spring. Please stay tuned to our website for official information on worldwide release.

  7. I never thought I would be this happy about a power supply. I have one more question though. I don’t see a 15v output option on either the Zuma or Ojai. Will it be safe for me to use something like this to upconvert the voltage from 9v to 15v for my oddball effects?

    1. @Zachary Drummond – You are correct that there is no 15V output option on our power supplies at this time. We have never tested them with this Voltage Converter and cannot provide any feedback on what kind of results you will see by using this device.

  8. For purchasing the Power Supply you can also visit another websites from you get best and highest quality products. Power Supply mounting brackets are designed to mount directly to the underside of the top of your Salvage Board, these brackets are of the highest quality. They are made from aluminum and ready to securely fasten many popular power supplying units.

  9. hi there¡¡¡ just want to ask if with any of this power supplies (specially ojai) can be used with a days chain for feed more than 5 pedals ( assuming that the current draw of pedals doesn’t require more than the 500 mA per output) will it be factible? thanks a lot and regards from mexico¡¡¡

    1. Hi Angela,

      Can you please answer this question as I am very interested with the answer. Will it also be noise-less if we daisy chain one output feeding 2 or 3 low power consuming pedals.

      1. @Martin Martinez and Marc – Yes, you can daisy chain other pedals to the same power output as long as they are all analog pedals. Digital pedals require isolated power outputs for noise free operation.

  10. Regarding Eventide pedals, it was mentioned above that “you would need to get a reverse polarity center positive” cable to power them……but you made no mention if you were going to offer such a cable.

    So is Strymon going to offer reverse polarity center positive cables for the Zuma/Ojai? Or will the standard cables from other manufacturers such as VooDoo labs work with the Zuma/Ojai? Standard 2.1 mm plugs on the Zuma/Ojai ?

    just want to be sure what will and won’t work as the answer provided above (saying you will have to “find” one) isn’t very reassuring to the many of us that own both Strymon AND Eventide pedals….basically i don’t want to get “Apple’d” into a closed “environment” with a power supply and not be able to get extra or “special” cables for it lol….


    1. @Ray – We do plan on providing a line of different cables and adapters for use with other pedals such as Eventide. Currently existing 3rd party cables and adapters will work with the Ojai/Zuma to power these pedals.

  11. Hi guys – I have a gig rig g2 – can I power its 1000 ma by daisy chaining 2 outputs on Zumba or Ojai ? I am currently powering it with its own gigrig generator ,If I can power it from the Zuma or Ojai, I don’t have to run 2 IEC power leads to my pedalboard …. Thanx

    1. @Nick – You can connect the Ojai to the courtesy output on the back of the PP2Plus as it is a direct line to the wall outlet.

  12. Can this power supply power the infinity looper, which takes 18v/300mA/center negative polarity. I have ordered this but I’m not sure if it’s the write power supply.

    Thanks for help

    1. @Ahmed – The Zuma can certainly provide 18V center-negative with the adjustable outputs however it is ‘rated’ at 250mA when set to 18V. In the chance that the Infinity looper does not require the full 300mA, you should give it a try.

  13. I have a Klon Centaur with the weird headphone jack style power cable. can I power this pedal safely? If so, would you have a suggestion on were to buy one.

    1. @Joey Belczak – Thanks for supporting Strymon! 🙂 We currently do not offer a 3.5mm mini plug power cable, however, these are available online from third party companies. The ones I have found have a tip positive polarity, so just make sure that you get a cable with the correct polarity that will work with your Klon.

    1. @Erik – Each of the Moogerfoogers and the CP-251 require a polarity reversal adapter to provide center-positive power to the pedals. The Zuma’s outputs are all center-negative, so if you get a polarity reversal adapter for each of your pedals, you can power them all with the Zuma.

    1. Hi Joel,

      No, the Voodoo Lab mounting brackets will not work with our power supplies.

      We are currently in the process of manufacturing brackets for Zuma to mount onto the modern Pedaltrain series boards. We do not yet have a date for release, but they will be available soon. For the Ojai, you can use Velcro or Dual Lock to mount underneath your board due to its light weight and compact size.

  14. Hi where I can buy a cable (9 VDC, 500 ma, center pin positive) to connect an Eventide H9 with your Ojai?
    Thank you

        1. @Saul Robles Rios – Yes, as long as you use the proper polarity-reversal adapter with a 2.5mm barrel connector, it will power the Eventide Space.

    1. @Ed – That really depends on the pedals you are trying to power, their voltage requirements, and how much current each pedal draws. You can power 9 isolated pedals at 9V up to 500mA each, or 7 isolated pedals at 9v up to 500mA and with two additional outputs that can provide either 12V 375mA or 18V 250mA. You can also daisy chain analog pedals that do not require isolation from a single output up to 500mA for the 9V outputs, 375mA for the 12V outs, and 250mA for the 18V outputs. You can even use a voltage doubler to sum the voltage of the 2 adjustable outputs set to 12V to get 24V. Also, make sure to verify if your pedals require center-negative power which Zuma provides by default, or center-positive power which would require a reverse-polarity adapter to power your pedal safely.

  15. Hello –

    I received my Zuma; however, the included patches do not connect to my EHX HOG (9VDC 500mA).

    Is there a patch that will work w both the Zuma and the HOG?

    Thank you!

    1. @Claison — Yes, the Eventide pedals all use a larger 2.5mm barrel connector, and require center-positive polarity. You can use that polarity reversal cable on our store to power up the H9 without issue =).

  16. Can you combine 2 18v together to get to 500ma?
    Other than trying one at 250ma for an Infinity Looper 300ma required and hope it doesn’t burn up is very unsettling.

    1. @Michael Seven – Yes, you can use a current doubler to combine the current from 2 outputs set to 18V to get 500mA of current. However, the Infinity Looper we have here works fine by connecting to a single output set to 18V on Zuma.

  17. i have been using Ojai for 9 months or so. adaptor cable from adaptor to ojai box was loose and would just fall out and I’d lose power. Got a second cable to replace the first one and it too just falls out, as I discovered live and lost all power during a set.

    1. @Kevin Rutmanis – Sorry to hear that you have been having trouble with your Ojai power supply. From what you describe, it sounds like at least one of the jacks on your Ojai or the Ojai’s power supply has been damaged. If you remove the link cable and look at the 24V jacks on Ojai and its 24V power supply, check to see if the center-pin has been broken off.
